Detailed Explanation of Key Technical Points for Spring Management of Ma Walnut Trees
I. Planting of Ma Walnut Trees 1. The suitable time for planting is from March to mid-April, after the soil thaws and before the buds sprout. Early planting makes it easy to survive, with deep rooting. When choosing a site, the specific environmental requirements for walnut growth and development should be considered. The orchard site is best chosen on sunny flat land or gentle slopes, with sandy loam soil being ideal, and requires a soil layer of more than 1 m, with the groundwater level more than 2 m below the surface. The planting area should be leveled, aged, and measures taken to prevent alkalinity and waterlogging. For mountainous areas, fish-scale pits can be built first, then the tree discs gradually expanded. Before planting, large pits must be dug and sufficient base fertilizer applied. The correct method of digging pits is: dig pits 80-100 cm square, keep topsoil and subsoil separate, and apply one small cartload (50-100 kg) of barnyard manure organic fertilizer per tree. When backfilling the pit, first fill with topsoil mixed with base fertilizer, then fill with subsoil, tamping while filling, and water thoroughly before planting.
